Roasting the scientist as part of his death sentence for illegal experimentations and overall crimes against humanity/minifigkind.The cop squad sentences the skeleton sheriff to death for obstruction of justice and proceed to gun him down (given that I've got any control over them).

So as I drive closer to the first set of obstacles and if Zahru was unable to be freed, I swipe the side of the Bone Sherif's car to not only dislodge the cage but run the Sherif off the road and into the awaiting police force and/or that light bley wall. After that, failing to shake the Bone Sherif off or not, I'll cruise straight past gap between the bley wall and the sand-green roof. That green strip straight ahead looks like a spiketrap or someshit so we'll do a hard-right.
